Twain's summer home...Quarry Farm is located in Elmira, New York. In 1869, Jervis Langdon purchased it as a vacation home for his family. When he died the following year, it was inherited by his eldest daughter, Susan Langdon Crane, Mark Twain's sister-in-law. Twain and his family summered there for more than twenty years. He wrote much of his work in an octagonal study built expressly for him, apart from the main house, in 1874. The study has since been moved to the Elmira College Old Campus in order to protect it from vandalism.

Mark Twain visited Africa on two separate journeys.  This, his first visit, he writes about in "The Innocents Abroad".  He actually visits the continent twice on this trip.  At its furthest point he visits Egypt.  Of course, in the world of fiction Tom, Huck and Jim take a balloon ride over the Sahara in "Tom Sawyer Abroad".  Many years later Mark Twain visits South Africa, as written about in "Following the Equator".

Fairhaven was first settled in 1659 as "Cushnea", the easternmost part of the town of Dartmouth.
